Knee joint

The knee joint connects the femur, tibia and patella.

The knee joint also includes a joint cavity that is hermetically surrounded by a joint bag. And the reduced pressure inside the joint bag allows you to maintain the bone in a closed position.

Meniscus is a cartilaginous gasket that acts as a shock absorber in the joint, as well as stabilizing the knee joint.

When moving in the knee joint, the menisci contract, their shape changes.

Shoulder joint

The shoulder joint is a typical example of a spherical joint - one of the articular surfaces is represented by a convex spherical head, and the other, respectively, a concave joint cavity.

The spherical joint is the most mobile of all joints, movement in it can occur around many axes.

Temporomandibular joint

The unique formation of the temporomandibular joint is the intra-articular disk, which, merging with the joint capsule, separates the cavity of the articular capsule into two separate sections and ensures accurate sliding of the bones along each other.

Ankle joint

The ankle joint is the most sensitive and important mechanism in the anatomy and structure of the foot, which consists of bone muscle and tendon formations, with their joint established work it is possible to move the foot, maintain balance and stability in an upright position.

Brush

Due to the fact that there are many bones and they are small, the brush has such plasticity and mobility, but because of this, with injuries, the performance of the hand is noticeably reduced.

Crunch of nitrogen bubbles in joints

What can crunch when you bend your knees, especially when you do a charge?

Perhaps the best explanation for this phenomenon is the theory associated with air pressure and nitrogen. All your joints contain air and fluid.

Nitrogen is a major component of both air and joint fluid. When you get up (or make other movements), the pressure in the joint changes and nitrogen forms tiny bubbles.

Sometimes there is enough earthly attraction for these bubbles to form. Crunch is the sound of a bubble moving.

For example, when you rise in the morning from a bed in which you lay all night, nitrogen and air move, reacting to gravity.
